Performance and emission characteristics of gasoline engine fueled with hydrogen peroxide emulsion

Gasoline engines have been one of the main contributors to the increase in greenhouse gas emissions. In the present study, the potential benefits of hydrogen peroxide (H2O2) on performance and emission were explored in a single-cylinder gasoline engine. Experimental results pertaining to the influence of H2O2 emulsification on performance and emissions at a constant engine speed of 3500RPM and variable loads are presented in detail. The results indicate that emulsified H2O2-gasoline blends have shown higher in-cylinder pressure, increased heat release rate, and prolonged start of combustion. It also contributes towards higher peak pressure, an increase in gross indicated work, and thermal efficiency. Furthermore, the results also show that emulsified H2O2-gasoline blends promote lower concentration of CO, HC, and NOx emissions as compared to that of gasoline alone operation.
